Firefox 4 has released a video that shows ants running around:

So I ran it on my MacBook 2.4GHz Core 2 Duo on each of my browsers:

  • Firefox 3.6.12 = 40 fps - drops to 12 over time
  • Firefox 4b7 = 80 fps - stays fairly constant > 70 fps
  • Safari 5 = 90 fps - stays fairly constant > 85 fps
  • Chrome 7 = 110 fps - moves between 100 and 140 fps

Now I don't know the validity of this test as a basis of real speed comparison, but if one was to take those numbers as is, it shows that Firefox 4 is the slowest of the new browsers.

I am making no judgement at this stage, just printing the numbers I found.
